What move is this?

I was watching the intro video at Eddie Bravo's website, http://www.thetwister.tv/10PJJ.htm, and saw one of his students trying to set something up from rubber guard at 5:14-5:15 that I've never seen before. Unfortunately, the video cuts to a different scene before he does whatever he was trying to do. Does anybody have any idea where he was going with this?
